GRAND RAPIDS, MI – Mitt Romney's Tuesday visit to Holland State Park could be marred by protesters affiliated with the political action committee MoveOn.org.

Supporters of the progressive group are mobilizing ahead of the last leg of Romney's five-day bus tour through six swing states that the presumptive Republican presidential nominee has dubbed "Believe in America: Every Town Counts."

The group has held parallel stops with the Romney campaign and is gearing up to do the same in Ottawa County, often referred to as one of the most Republican municipalities in the country.

As Romney uses the park backdrop and the iconic Big Red lighthouse to talk about his vision for defeating President Barack Obama and the future of the country, members of MoveOn will tout the GOP candidate as the "President for the 1%."

In an email message seeking to draw a crowd, MoveOn organizers say that a victory for Romney would be an "unmitigated disaster for the middle class and the economy."

"We need a president of the United States, not a president of the 1%, but Mitt Romney wants to lay off teachers and firefighters and gut Medicare, all so he can give special tax privileges to the wealthy," said Justin Ruben, the group's executive director. "How out of touch can he be? We need a level playing field where everyone has a fair shot at economic success, not more advantages and financial gain for only the 1%.”

It wasn’t immediately clear where the protesters will congregate, but the group points out in the communication that if they begin to gather at 5 p.m. – the campaign appearance is to start at 6 p.m. – they stand the best chance of drawing the media’s attention.

The bus tour started Friday in New Hampshire and has swung through Pennsylvania, Ohio, Wisconsin and Iowa before ending here. Other stops in Michigan are in Frankenmuth and DeWitt.

Earlier rallies in other states have proved disruptive. The group had an airplane pulling a message saying “Latino Voter Purge = Racism For Romney” at one campaign appearance, the group said. MoveOn has also had a Cadillac driven by 1%ers with NASCAR-style decals of Romney’s largest corporate sponsors and a dog strapped to the roof, according to the group.

The anti-Romney presence also has fueled a last-minute switch in the location of a stop in Pennsylvania and drawn attention in Ohio.

The Ottawa County venue was selected for its natural beauty, according John Sellek, Romney’s state director. Romney is visiting well known spots at every tour stop.

“In Michigan, one of the most iconic, most photographed places in the state is Holland State Park and the Big Red lighthouse,” Sellek said. “There’s no other place like it on earth and we want to show off its beauty and share it with the country.”
