Manchin wanted a $4 trillion infrastructure bill (almost double what Biden is proposing) but now doesn't want to pass it without Republicans (who want a $600 billion bill) because they stormed the capitol.
In 2011 Manchin voted for a talking filibuster, right now he doesn't want to budge at all. "I will not vote to eliminate or weaken the filibuster".
Manchin argued for 28% corporate tax when Obama was in charge but now it's too much (can't find an article for this but I remember seeing it somewhere).
He's been on this Bipartisanship over everything since he's been in office. Both WV senators rank high in bipartisanship scores.
Clearly WV voters value you that over any single initiative.
Capito, Manchin rank among most bipartisan senators - WV MetroNews
He was just elected in 2020, his positions on Bipartisanship have not changed significantly since his election.
He's on record saying he wants to limit progressive overreach:
For Manchin, a Divided Senate Is a ‘Golden Opportunity’ for Action
As far as your misrepresented cherry pick from his op-ed, he's right in many ways.
"I simply do not believe budget reconciliation should replace regular order in the Senate. How is that good for the future of this nation? Senate Democrats must avoid the temptation to abandon our Republican colleagues on important national issues," Manchin wrote.
"Republicans, however, have a responsibility to stop saying no, and participate in finding real compromise with Democrats."
Regarding January 6, he's right non-functioning government and legislators leaning in on tribalism is only going to lead to more fukkery.
"You can't have this many people split to where they want to go to war with each other," he told CNN, as he calls for Democrats and Republicans to work together on top legislative priorities
Now he has to convince his friends to come to the table with serious talks or he will ultimately become more of the problem with non functioning government.
