Alexi Giannoulias at Crystal Lake's Independence Day Parade.

Mark Kirk at Crystal Lakes' 4th of July Parade. He will be in Lake in the Hills' parade Saturday morning.

Here’s how Time Magazine summarizes the race:

“Giannoulias and Kirk, both of whom have been dogged throughout the campaign by controversy, are tied at 34 percent in a new Chicago Tribune/WGN-TV poll, while more than one in five voters remain undecided. Green Party candidate LeAlan Jones earns the support of 6 percent of voters, and Libertarian Party candidate Mike Labno earns 3 percent.”
