Donald Trump's days of dominating the silver screen are all but over.
Trump's share of GOP airtime may be up to 70 percent, but that doesn't tell the whole story.
The real estate mogul has gained a considerable lead in the race for the Republican nomination with the help of the on-screen time.
Over the last 30 days, Trump leads the pack for most mentions at a 75 percent clip.
However, it hasn't impacted his poll numbers by much.
It could be that Trump has hit his ceiling, or that attack ads have been taking their toll on his campaign for presidency.
