Angus King of Maine is an Obama crony and all-around corrupt piece of shit. He has been the beneficiary of 9 digits' worth of taxpayer-financed green energy scams.
The reasons why he is doing so well in the polls are:
Media support.
Maine has a lot of TV-addled boomer retards who will vote for anyone who pretends to be an 'independent' even though he votes like a commie. Angus never saw a spending bill he didn't like. Especially when he gets kickbacks.
Soros helped finance ranked choice voting, which will now allow votes for commie Zach Ringelstein to cascade to Angus King. Because of all the complex ways the vote could play out, all the ballots will have to be shipped to Augusta, where they will be counted by liberal activists. Trust them.
The challenger, Eric Brakey, is young and doesn't have the name recognition of Angus King. Brakey is essentially a Libertarian running as a Republican. This makes him a viable candidate in Northern and Western Maine but the coastal liberals aren't going to vote for him because he likes guns and freedom and doesn't like welfare, Obama, etc. I believe Brakey is genuinely patriotic and not corrupt. Therefore, he has to swim against a tide of shit.
Realistically, the only way Brakey can win is if we get a whole bunch of indictments unsealed between now and November and normies are so outraged by the revelations that the Blue Wave turns into a Tsunami of Blood.
