AUSTIN, Texas -- Labor Day has come and gone and that means we're now just two months out from Election Day. 

Get ready for the continuous onslaught of campaign ads hitting the airwaves - or in another case, the roadway. In just 24 hours a GoFundMe campaign raised nearly $10,000 to construct a mobile billboard that will plaster a 2016 tweet from President Donald Trump criticizing Texas Sen. Ted Cruz.

It was that tweet that got one Texas liberal activist thinking: get that tweet plastered on a billboard on a Texas highway. Houston Latino community organizer Antonio Arrellano was behind the campaign.

"We went to a mobile billboard that will, as of right now, be focusing in Dallas, Houston for the first leg, and then expanding from there on to make sure we get as much visibility as possible," Arrellano said over the phone. 

It comes as the president gets set to campaign for Cruz in an October Texas rally. But Republicans don't seem too worried about the social media traction the proposed billboard has gotten.

"Billboards are a low priority way to communicate with voters. They get attention from a social media standpoint, but they don't do much to move votes," said Travis County Republican Party Chairman Matt Mackowiak.  

Mackowiak said an ad dropped Tuesday morning by Cruz allies will be far more effective. It was fully funded by the influential conservative organization Club for Growth and takes direct aim at Cruz's Democratic challenger, Beto O'Rourke.

"Clearly this is an attempt for the Club for Growth to try and increase the negatives that O'Rourke has among the electorate. So far he's had a lot of national attention. His positives have gone up. His negatives have not gone up and that's because no one has attacked him, but that's now changing," said  Mackowiak.

O'Rourke has said he won't go negative but that's not stopping allies like Arrellano. He saID he and his team are getting rolling on the ad that was funded literally overnight.

"The billboard will be on the road across Texas highways as soon as Thursday of next week," Arrellano said.
