The “stimulus package” not getting any Republican votes in the house is pretty encouraging. It shows that a) the Republican leadership was able to get some solidarity, and b) that the Democrats were ineffective at getting any Republicans to join them.
The important thing over the next few years, though, is not to just oppose everything the Democrats do, but to have and push big ideas of their own. The Democrats managed to get away with just opposing everything, largely because of a media that was behind them, which made it easy to paint anything the Republicans were doing as bad. The Republicans don’t have that luxury, and are going to have to demonstrate that there is a better way than the Democrats are proposing.
