Two differences:
1. Cantor has much more experience than Obama. Attacking experience would be difficult for Obama.
2. Dan QualyE was a poor choice because he permitted himself to get labeled as “stupid” pretty boy. That’s just not going to happen with Cantor -— because -— and this is bigoted —— he’s Jewish and Jews are sterotyped by the MSM as eggheads. Turn that negative into a positive.
The MSM hates Cantor and calls him a “Bush Attack Dog” all the time. That’s good enough for me.
However, your point #1 could be said of your local pharmacist or store manager.
