There are many reasons for making a voting choice. Some people vote ideologically. They recognize whether they are liberal or conservative and then relate that to the candidates. The party platforms help make the linkage clear. One party seeks to have government regulate, coordinate, allocate and support solutions to societal problems. The other party and ideology asserts that free market forces, individual responsibility, and restriction of governmental roles in life will get the problems taken care of.
Others vote on an evaluation of individuals. They claim to support the "best person" without regard to ideology or party. That sounds wonderful but with a little bit of probing proves totally impractical for the many down-ballot decisions which will need to be made on election day. Then the vote becomes a measure of what name sounds good or which candidate had the most campaign signs on the street. Not a good criterion.
And, a large number of voters are retrospective. They vote on what an incumbent has done. If they like what has been achieved, they vote to retain. If they are unhappy with the performance, they vote to oust the perpetrator.
So, here's a record to run on:
Senate Laziest and Least Productive in Decades
That would be the Democratically controlled Senate; the one under the august leadership of Harry Reid who simply ignores any of those pesky bills seeking to cut spending, pass a budget or deal with critical issues.
It's a good thing the country is enjoying a booming economy, full employment and a world filled with peace and love.
