Three voters give their thoughts on the past two tests of presidential mettle and on what lies ahead. When  Iowan Brad Cranston last joined the program, he was disappointed by Bachmann withdrawing her bid but was shifting towards Santorum. Staunch Gingrich supporter and New Hampshire resident Karen Gallant – who lived in Massachusetts during Romney's governorship – remains unimpressed by the GOP frontrunner. And South Carolinian Karen Martin is currently unenthusiastic about any candidate.
