The anger among people in Gujarat against the implementation of the Goods and Services Tax (GST) is an indication that the BJP would face a stiff challenge in polls, scheduled to be held in December, he said.
Mr Raut was addressing a discussion on a TV channel.
"Congress leader Rahul Gandhi is capable of leading the country. It is wrong to call him 'Pappu'," he said referring to the nickname used to mock the Congress vice-president by a section on social media.
State Education Minister and senior BJP leader Vinod Tawde was also present at the event.
"The biggest political power in this country is people... the voters. 'Woh kisi ko bhi Pappu bana sakte hai' (People can make anyone pappu)," the Shiv Sena leader said in an apparent dig at the BJP which had secured a massive mandate in 2014 polls.
Shiv Sena, the oldest constituent of the NDA, shares a 'blow hot-blow cold' relationship with its senior ally, the BJP, in the Centre and Maharashtra.
Mr Raut's comments came a day after the schedule for Gujarat polls was announced.
Though Sena lacks any base in Gujarat, the home state of PM Modi, the party had extended its support to Patidar leader Hardik Patel who had met Uddhav Thackeray at the latter's residence in Mumbai earlier this year.
"The Modi wave was there in 2014 general elections but now it seems to have faded away. The way people are marching on roads of Gujarat after GST was introduced, it seems they (BJP) are going to face a challenge," Mr Raut added.
In 2015, Sena had said that even 100 Rahul Gandhis cannot match Prime Minister Narendra Modi's "mega wave" and had mocked the Congress vice president for his 'suit-boot ki sarkar' jibe.
