Nationwide Rash of Attacks on Republican HQ's

Kudos to Michelle Malkin for mentioning the scores of random attacks occuring across the nation. In her latest blog entry, she mentions a new group of folks that have threatened, intimidated and stolen from Republican HQ volunteers and staff. She also links to two other entries, including a post regarding the attack on the Alachua County Republican Chairman by a pugnacious Democrat instructor from the local community college. Is it frustration that is causing such illogical outbursts?
