Shelton's popularity likely helped lead Jermaine Paul to victory in Season 2. Then, in Season 3, he was aided by the built-in fanbase of Cassadee Pope, who previously gained success with the band Hey Monday.
But last season, Blake Shelton used a specific strategy to nab his third straight victory. He consistently eliminated stronger but non-country singers from his team in the battle rounds, so by the time he reached the live shows, he only had artists in his wheelhouse.
Blake Shelton claimed that this was because he knew the most about promoting country singers, but there may have been a bigger strategy in play. Country singers almost always do well on music reality shows, so Shelton likely knew he stood the best chance of winning if he stuck with this genre.
As John Kubicek of BuddyTV noted, Blake Shelton also used a smart strategy last season with song choices. For Danielle Bradbery in particular, he chose songs that both older and younger viewers of The Voice would recognize. But he also picked tunes that people might not already have on their iPods. This, in turn, encouraged those fans to download Bradbery's versions of the songs. This was key, since iTunes downloads count as votes on The Voice.
This prior success has not gone unnoticed. Blake Shelton's fellow coaches are gunning for him more than ever in The Voice Season 5. This includes Usher, who lost to the country star in Season 4. Usher is not judging Season 5 but will reportedly be back for Season 6.
But Blake Shelton will not be torn down anytime soon. He already snagged an early favorite for his team last night, stealing E.G. Daily from Cee Lo Green during the blind auditions. Like the aforementioned Pope, Daily has a built-in fanbase following a long career in Hollywood. She is perhaps best known for playing Dottie in Pee-wee's Big Adventure and providing the voices of cartoon characters like Tommy Pickles on Rugrats and Buttercup in The Powerpuff Girls. She also sings as young Jake Harper in the theme song for Two And A Half Men.
Throw in the fact that E.G. Daily is a country singer, and Blake Shelton may have the recipe for success on The Voice Season 5. Per Internet spoilers, she has already made the Top 48.
It must be noted, however, that Daily and Shelton may face some backlash, particularly from those upset that Daily is a so-called "ringer" who already has plenty of experience. Similar backlash against Judith Hill, a former duet partner of Michael Jackson, likely led to her early elimination last season.
