It’s not that Maryland’s incoming freshman representative Andy Harris doesn’t like government-based health care, it’s that he doesn’t like the U.S. health care system. Neither do I. Maybe a Democrat is a Republican who had to wait a month for open enrollment.

I’m updating nine House races to reflect the newest public polling and news reports. (Yesterday’s update can be found here.) Overall, the individual polling data today has not been good for Democrats. Each day’s new updates are highlighted in green.

Today effectively marks the end of the primary election season and the true beginning of the general elections. It’s not only one of the last primary days but one of the biggest, including Delaware, District of Columbia, Maryland, New Hampshire, New York, Rhode Island and Wisconsin. [Ed. note: Jon will be liveblogging results all night. Delaware polls close at 8pm EDT, with a number of others closing at 9. Look for results and reaction at FDL's Elections page.]
