It has been revealed today that ad spending for Super Tuesday alone has reached $10million. Mitt Romney has spent approximately $6.3million on negative ads, and it is estimated that $16.4million has been invested on negative ads alone by the Restore Our Future campaign, a Super Political Action committee overseen by former Romney advisers. Super PACs have the freedom to spend an unlimited amount on advertising under the condition that they do not directly converse with the candidate. Although it has been pointed out that Clinton and Obama viciously attacked each other in the Democratic race of 2008, the harshest of comments are usually saved for the general election. The 'Restore Our Future' campaign has chosen to attack fellow Republicans, sending out messages which claim that 'Newt Gingrich has more baggage than the airport'. The aggressive style of the Romney campaign has been on display in several made for Web videos discussing Barack Obama's leadership, it has also created trending topics on Twitter to attack Gingrich such as #grandiosenewt.
