The want to dirty him. Same as having the KKK offer their support. They're not trying to help you.
The dems want a liberal in the senate, and especially if they think their guy might lose. So, they'd rather have Hillary run against Romney that against Cruz.
Dems are very good at hedging.
Even when they lose they seem to win.
Not only do they have a majority in the senate, but nearly all of them vote in lockstep with the leadership. There’s no more conservative Dems in the senate.
While on the GOP side one has to look hard to find a true conservative. It’s pretty disgusting and disheartening.
The media controls the narrative and it’s clear that far leftists are left without labels while conservatives are called extremists.
It’s tough to fight public perception that is so heavily shaped by the MSM.
