ICE outrage in Maine today A young man was needlessly and senselessly shot and killed. The ICE agents involved and their supervisors must be held accountable. ICE should be dismantled and only reconstituted if part of a larger, just, and comprehensive immigration reform package. #MEpolitics

Suggestion: use ME’s ranked choice voting to determine G. Platner’s replacement. The simplest, least time-consuming way to involve the most voters (June primary 220,000+) in the process and guard against the Party’s nominee being chosen via a low-turnout caucus or by Party leaders #MEpolitics

It’s well past time we mended a broken Washington. Before Trump it was endless gridlock. Since Trump, it’s been increasing chaos, incompetence, and corruption. To fix Washington, let’s start by replacing “concerned” senators like Susan Collins with REAL CHANGE reform advocates like me! #MEpolitics

LET’S DEBATE!!! Maine’s US Senate race is not settled and appears to be tightening. ME’s primary election is next week and there’s still time. The cancelling of the 5 prior debates cut short important policy discussions and shortchanged ME voters. So, LET’s DEBATE costelloforsenate.com #MEpolitics

Climate change is real. Largely human caused and already an existential threat to many communities and livelihoods. To tackle climate change we must implement an aggressive, science-based plan to markedly curtail greenhouse gas emissions globally and pull carbon down from our atmosphere. #MEpolitics

Housing problem: Maine median incomes up only 50% over past decade; home prices up 110%, due to limited inventory and slow construction. Solutions: state & local permitting and reg reforms; boosted wages; more ME and fed $$$ for home construction and ownership; and lower interest rates #MEpolitics

Canadian visits to Maine have fallen by more than 25%. A drop with severe repercussions for Maine’s tourism industry. With summer upon us it’s hard to see those numbers improving unless Trump alters his ill-tempered rhetoric and policies (He doesn’t care!). To fix, change Congress! #MEpolitics

Costly War! Looks like the Trump Admin is being forced to accept a peace deal with Iran that’s likely to leave most involved, except Iran, in a strategically worse position than was the case after the JCPOA deal negotiated by the Obama Admin in 2015. The deal scrapped by Trump in 2018. #MEpolitics

The Trump DOJ’s $1.7Bn taxpayer funded “Anti-Weaponization” Fund to compensate Trump supporters who claim to have suffered at the hands of the Biden Admin would be considered laughable - if it weren’t so wasteful, unethical, and outrageous. Congress must end this self-serving madness! #MEpolitics

Two of the most exciting things I did as a boy growing up in Maine was to learn how to hunt and shoot responsibly. And I’ve always supported lifesaving, common sense gun safety laws, including universal background checks, waiting periods, red flag provisions, and assault weapons bans. #MEpolitics

Plausibly, humanity is facing 3 existential threats: nuclear conflict, unbridled AI, and climate change. Yet, the power and retribution focused actions & inactions of the Trump Admin and GOP congress are exacerbating, not mitigating these threats. The fix, vote against them this fall! #MEpolitics

Neither JD Vance nor Susan Collins are “doing a great job.” Both are tied to an unprecedentedly corrupt, reckless, and harmful presidency... And Collins’ oft expressions of “concern” aren’t sufficient, particularly given that she’s voted with the Trump Administration 95% of the time. #MEpolitics

It’s important that Pres Trump’s interest in cutting business deals (corrupt Trump Org & other deals) with China not undermine US support for Taiwan and allies Japan and S. Korea. Democratic nations that serve as a key bulwark against an increasingly aggressive and authoritarian China. #MEpolitics

Trump Admin has cut aid to Ukraine by roughly 99 percent and shamelessly cozied up to Putin. Even allowing Russia to benefit financially from our costly war with Iran. Good news: Ukraine is becoming more self-reliant and mounting a more effective defence against Russia. Slava Ukraini! #MEpolitics
