It’s the unrealistic expectations and demands of the purists that leads to defeat. Look at McCain’s and Romney’s defeats. When we all are reasonable and work together we achieve victory as we did with Bush’s presidency and capture of the House and Senate. That is winning.
What universe are you living in??? Those two were/are hardly "purists".
When we all are reasonable and work together we achieve victory
And what victory is that??? a compromise that undermines the citizens of this nation??? Sounds like you have been slurping at the DU trough. Wipe your nose. It's showing.
