They just sold out the voters who elected them to uphold conservative principles.
Say what you want about Joe... he did what his constituents expected him to do... the only reason the House and Senate are in the hands of the Democrats is because Republicans failed to deliver on what their constituents expected them to do. (i.e. control spending)
I agree with you on the Republicans failures.
I’m also saying: If Lieberman is going to speak at the Republican convention, he can caucus with the Republicans in the Senate.
