If Sonia Gandhi had attended Ram Mandir Pran Pratishtha, she would have lost 80-85% (existing) Muslim votes to other parties like SP, NCP, RJD, JDU, etc.

After rejecting the invitation she won't lose any single (existing) Hindu votes.

Remember Nehru who call himself Pandit refused to go to Somnath Mandir rebuilt by Sardar Patel, the same Sonia Gandhi doing today but Hindus have been voting them before and even now

Rahul Gandhi was always right when he said Congress is a Muslim Party and Manmohan Singh said that the first right on resources are that of Muslims. But Hindus never wake up to reality

Nehru visited Babur's grave in 1959

Indira Gandhi visited Babur’s grave in 1968

Rahul Gandhi, Manmohan Singh and his Foreign Minister, Natwar Singh visited the grave of Babur in 2005.

Also Congress sent their representatives to Vatican to attend some ceremony in 2016.

Despite all the wrong doings still Hindus votes for them

This difference is the reason why a few foreigners managed to rule on Bharat for centuries. Secular Hindus are more responsible for the bad condition of Hindus than outsiders.
