She hasn’t said she is running for the Senate.
Liberals want Sarah Palin to run for the Senate or be on Fox, anything to keep her from running for President against Hillary. that is what they fear. As president she could veto a lof of the socialist agenda. as a senator she is one vote out of a 100. As president she could rein in the EPA to let capitalism use the unlimited oil in shale we have . that is just 2 examples but many more.
But she did say she is thinking about it and may run if a better candidate doesn’t emerge.
While that’s true we need more counters to the Rubio/McCain rinos in the Senate.Plus she could turn yet another seat from socialist to Republican.I think its a good move.
