With just under 30 days until the first nominating contest in the country, the ad war in Iowa is officially heating up this week as four campaigns are pouring in cash and air time to try to boost their standing through television spots airing across the state.

Former Speaker of the House Newt Gingrich, who leads the Republican pack in the Hawkeye State, will release his first television ad Monday. Titled “Is The America We Love A Thing Of the Past? Newt Says No,” the minute-long ad will appear statewide on broadcast and cable with an ad buy of $250,000. It is unknown how long the TV spot will run. Gingrich currently sits atop the Republican field but has yet to promote himself via advertising this campaign cycle, relying instead on media coverage of his speeches and debates.

But Gingrich is not alone when it comes to making an advertising push in the state for the first time this week. Mitt Romney’s campaign announced last week that they would roll out their first advertisement, titled “The Right Answer,” in Iowa. A source tracking campaign ad buys told ABC News Romney has purchased $252,000 in broadcast in the Cedar Rapids, Des Moines and Sioux City markets along with $13,000 in statewide cable on Fox News that will run for a week beginning Wednesday through Dec. 13.

Romney, who has decreased his presence in the state compared to last election cycle, placed third in the most recent Des Moines Register poll released this weekend behind Gingrich and Rep. Ron Paul, who is pouring $429,000 in advertisements on broadcast and cable for two weeks, running from Monday through Dec. 20, according to a source with knowledge of the buy.

But as each of these candidates increases their presence on television in the coming week, one candidate has flooded the airwaves for over a month without reaping any benefits in the polls. Perry, who has run ads in Iowa since the last week of October and invested the most in advertising nationally, clocked in with only six percent in the most recent Des Moines Register poll, tying with Rick Santorum for last place among candidates competing in the state.

The Texas governor has spent $3.5 million dollars nationally in advertisements, with the bulk of it being in the Hawkeye State. Perry’s most recent ad purchase totaled $89,000 for his ads called “Faith” and “Energy Jobs” between Sunday and Tuesday, a source with knowledge of the ad buy told ABC News. Last Thursday, Perry also aired an ad drawing attention to his debate gaffe before and after he appeared on “The Tonight Show with Jay Leno.”

The pro-Perry super PAC, Make Us Great Again, has tried to promote the Texas Governor through television ads as well. Starting this week, the super PAC placed an advertising buy for the week of December 3 through December 11 at a value of $297,000 in Iowa and South Carolina. the ad, totled “Elites,” attempts to paint a contrast between the Texas governor and “Washington elites wrecking America” by highlighting his reform proposals that aim to balance the budget, simplify the tax code and free the country from its dependence on foreign oil. Make Us Great Again has spent a total of $1.1 million in advertisements touting the Texas governor.
