The Bharatiya Janata Party (BJP) has consistently led the seat tally in Lok Sabha elections in Karnataka since 2004. If the 2009 Lok Sabha elections is taken as the cut off, as that was the first election after delimitation of seats in 2008, the BJP has never lost 13 seats. The JD(S) has won one seat consistently, while the Congress does not have even a single seat that it has consistently won during this period.
The seats which the BJP never lost are: Bagalkot, Bengaluru South, Bengaluru North, Bengaluru Central, Belagavi, Vijayapura, Davanagere, Dharwad, Haveri, Koppal, Shivamogga, Uttara Kannada, and Dakshina Kannada. The JD(S) has won Hassan consistently.
Having been reduced to one seat in the 2019 parliamentary polls, the Congress lost many of its “safe seats” that year. Before 2019, Kalaburagi, Kolar, Chamarajanagar, Chickballapur, besides Bengaluru Rural, the sole seat they won in 2019, were considered safe seats for the Congress.
