This is dumb.
Democrats need as many D's as they can get in Congress. Regardless of Manchin's fault, you can rely on him to vote for the big, important legislation, you are not going to get that with a Republican.
From Wiki:
As a senator, Manchin is known for his bipartisanship, voting or working with Republicans on issues such as abortion and gun ownership. He has opposed the energy policies of President Barack Obama, declined to vote on both the Don't Ask, Don't Tell Repeal Act of 2010 and the DREAM ACT, voted for removing federal funding from Planned Parenthood in 2015 and against in 2017, and voted to confirm most of Donald Trump's Cabinet appointees.
You mean he only voted with the Democrats 95% of the time?Might as well be a republican.
I suspect he voted with the Democrats much more when Obama was popular and voted with the Republicans much more when Obama was unpopular.
Even at his least partisan, Manchin still votes with Democrats like 80% of the time. In WV is that really such a sin?
