Nice try, but Erlich has already proven that he’s perfectly capable of losing on his own. Democrat Martin O’Malley beat Erlich in November, 2006 after Erlich served a single term.
Now, 4 years later, we still have no slots revenue - while the surrounding states of PA, DE and WV pull in money from Marylanders. The bottom fell out of the slots market, and they received few bidders for licenses. Everything is still tied up in court and Marylanders are waking up to the fact that RAT politics sent this revenue stream down the crapper. They have seen how anti-business O'Malley is and they want a guard dog keeping an eye on the legislature.
In Maryland, a republican has to win by a huge margin to actually win - Baltimore City, in one election, just kept the polls open until the other districts had reported and they knew how many votes to "find". Ehrlich will need every vote he can get.
And he has a good chance - in the last four years, folks have gotten to know Nancy Lugosi - evil spawn of the currupt D'Alessandro machine, and started to get a clue how corrupt the 'Rats in MD really are.
