“why they have waited until now. “
Their polling indicates that their loyal base is not going to go to the polls this November. They need an issue to get their base energized. At this point they’re fishing with grenades. Frankly, I don’t see their base going to the polls regardless of the issue. Even the stupidest realize they’re being hurt by Democratic policies. Though the base won’t change their party or their votes because of the economic beating they will sit this one out and thus allow (I can’t say conservatives) Republicans to win.
What we really have to fear is the lame duck session after the election when none of the losers have any fear whatsoever. We need to do away with the lame duck sessions. A Republican congress gave us such gifts as the Department of Education after they lost the majority. If I recall, that was a Newt Gingrich production.
A very good image.
