If someone did this to me I would vote for the opposing candidate just out of spite.
As many would, and probably will in Iowa.
Telling someone they're getting an 'F' for not voting by a Washington DC politician = NOT SMART. Especially with all the anger at Washington DC these days for their not doing their job, missing votes, failing to stop Obama at anything, and being out on the campaign trail when they should be doing their job in Washington DC.
Yep, not smart at all.
